I have used the cyan for about 2 weeks now and have had no problems except for a little toner spilled during the install. Color looks ok when printed. I hope the other colors work as well once I need them.

I have used LD Product toners in my Dell 3100cn since the origional toners bit the dust. Many copies later I'm still satisfied. I have experirnced no problems so far with quality of the LD Products or the quality of printed pages.
